## Description
|
||
|
|
<section id='description'>
|
||
|
|
Up until now, you've looked at regexes to do literal matches of strings. But sometimes, you might want to also match case differences.
|
||
|
|
Case (or sometimes letter case) is the difference between uppercase letters and lowercase letters. Examples of uppercase are <code>"A"</code>, <code>"B"</code>, and <code>"C"</code>. Examples of lowercase are <code>"a"</code>, <code>"b"</code>, and <code>"c"</code>.
|
||
|
|
You can match both cases using what is called a flag. There are other flags but here you'll focus on the flag that ignores case - the <code>i</code> flag. You can use it by appending it to the regex. An example of using this flag is <code>/ignorecase/i</code>. This regex can match the strings <code>"ignorecase"</code>, <code>"igNoreCase"</code>, and <code>"IgnoreCase"</code>.

|

|
|
Write a regex <code>fccRegex</code> to match <code>"freeCodeCamp"</code>, no matter its case. Your regex should not match any abbreviations or variations with spaces.
